It was another bumpy day at the All England Tennis Club, with third-round play getting underway for some of the top competition.

Men's play

Top-seeded Novak Djokovic literally stumbled during his match against French Gilles Simon Friday, hitting his left shoulder hard on the ground during the third set. It somehow didn't stop him from finishing off Simon in straight sets, 6-2, 6-4, 6-2, and a medical exam after the match said he was just fine.

Andy Murray continues to play some of his best tennis ever at Wimbledon. Some thought his match-up against no. 27 Roberto Bautista Agut might be a challenge, but Murray quickly dispatched of him 6-2, 6-3, 6-2. The last game was the toughest of the match for Murray, engaging in a bit of a duel at deuce for a few points until converting a match point.

Marin Cilic delivered an impressive upset, knocking off no. 6 Tomas Berdych. In what was an engaging three-set match with two tiebreaks, Cilic powered through to the round-of-16 7-6, 6-4, 7-6.

Women's play

Friday knocked off some ranked favorites. Li Na, ranked second, winner of the 2014 Australian Open and first-round exiter of the 2014 French Open, lost in two tiebreak sets to unranked Barbora Záhlavová-Strýcová of the Czech Republic. Na challenged and won on what would've been the match point, only to lose the next on a double fault.

American favorite and five-time Wimbledon champion Venus Williams struggled against no. 6 Petra Kvitova. It felt as though #30 Williams was the higher ranked, but Kvitova easily won a second-set tiebreak to break through and win 5-7, 7-6, 7-5.

Agnieska Radwanksa, fourth in the tournament, continued to shine. She beat 21-year-old Michelle Larcher de Brito 6-2, 6-0, and has yet to drop a set in the tournament.
